For most of my life I've assumed that when builders wanted old buildings destroyed they used a wrecking ball like I'd seen in cartoons. Recently I've realized that I've never actually seen a wrecking ball being used. I don't even know if they exist any more. I know that for big buildings they use explosives. And now I know that for small buildings such as this, they just knock it down with machines. This machine was picking up that big piece of cement and rebar, holding it above the building and then dropping it. In the photo it has just dropped the big chunk of cement. (This makes a lot of noise and dust and looks like it would be fun to do, for about an hour. Then it would be nice to go and have some milk and cookies and a nap....) The building being demolished here was a parking garage attached to what is now becoming "The Hudson" (inner city heritage restoration condo/loft living).
